Does Implant Design Improve Postoperative Flexion?

2014-08-27 03:42:21 | BioPortfolio


This study will evaluate whether design features of one implant design allows more knee bend than the other. Patients will have 1 design in the left knee and 1 design in their right knee. Both knee surgeries will be on the same day.


The primary objective of this study is to determine whether the passive, non-weight-bearing flexion is superior with the posterior-stabilized PFC® Sigma™ RP-F compared to the posterior-stabilized PFC® Sigma™ RP in bilateral Subjects receiving both implants and if this difference is a function of implant design.

Medical and Biotech [MESH] Definitions

Replacement of the knee joint.

Partial or total replacement of a joint.

Arthritis in children, with onset before 16 years of age. The terms juvenile rheumatoid arthritis (JRA) and juvenile idiopathic arthritis (JIA) refer to classification systems for chronic arthritis in children. Only one subtype of juvenile arthritis (polyarticular-onset, rheumatoid factor-positive) clinically resembles adult rheumatoid arthritis and is considered its childhood equivalent.

Partial or total replacement of one or more FINGERS, or a FINGER JOINT.

An instrument used to assess the results of rehabilitation from knee injuries, especially those requiring ANTERIOR CRUCIATE LIGAMENT RECONSTRUCTION. It measures recovery of knee joint function based on ACTIVITIES OF DAILY LIVING.
